There is a W kN/m load(including self weight) along a Beam and Beam length is L (m)and both ends of the beam are fixed.What is the maximum Bending moment and shear force of the Beam?
Maximum bending moment is (W*L^2) /12 kNm Maximum Shear force is WL/2
A ball release from the top of the building directly to the ground and it hits the ground after 10s .what is the height of the Building? (Take g=10ms^-2)
S= ut +(at^2)/2 u=0 ms^(-1) ,t=10s ,a=10ms(-2) S=travel length(Building Height) S=0*10 +10*(10^10)/2 =500m Building height is 500m
needs and Sandun will reply soon.
